MITRE ATT&CK

T1059.001 PowerShell T1204.002 Malicious File T1566.002 Spearphishing Attachment

This PDF file contains embedded JavaScript triggered by the OpenAction, a common technique for exploiting PDF vulnerabilities. The critical heuristic CVE_2009_0927 indicates a known exploit targeting Collab.getIcon. The embedded JavaScript stream, identified as javascript_obj0013_001.js, is likely responsible for downloading and executing a secondary payload, as suggested by the ClamAV detection as Pdf.Dropper.Agent-7256685-0. The use of unescape() further points to obfuscated malicious code.

Heuristics 7

Collab.getIcon — CVE-2009-0927 critical CVE exact CVE_2009_0927

PDF JavaScript calls Collab.getIcon — CVE-2009-0927 is a stack buffer overflow in Adobe Reader triggered by Collab.getIcon() with a crafted argument. Allows arbitrary code execution. (matched in decompressed stream)
ClamAV: Pdf.Dropper.Agent-7256685-0 critical CLAMAV_DETECTION

ClamAV detected this file as malware: Pdf.Dropper.Agent-7256685-0
OpenAction trigger high PDF_OPENACTION

PDF has an /OpenAction — code runs automatically when opened
unescape() call high PDF_UNESCAPE

unescape() found — often used to decode shellcode in PDF JS exploits (matched inside decoded stream)
JavaScript action low PDF_JAVASCRIPT

PDF contains a /JavaScript action. Generic JavaScript is common in benign forms; specific dangerous APIs are scored by separate rules.
Embedded JS stream low PDF_JS

PDF references a /JS stream. Generic JavaScript is common in benign forms; specific dangerous APIs are scored by separate rules.
